That’s something that’s said in nearly every post we’ve ever had about anything remotely controversial (just look at the uproar when we posted recent kurzgesagt videos). My moderation isn’t going to stop folks generalizing like that.
To answer your original question, if the responses to a post became nothing but a discussion about whether or not we should even consider an author or group, I’d be far more likely to split that into a new topic than to remove the discussion.
